Fundamental Studies of Strength Physics--Methodology of Longevity Prediction of Materials under Arbitrary Thermally and Forced Effects
Petrov, Mark G.

Thermally activated analysis of experimental data allows considering about the structure features of each material. By modelling the structural heterogeneity of materials by means of rheological models, general and local plastic flows in metals and alloys can be described over. Based on physical fundamentals of failure and deformation of materials that are revealed by thermally activated analysis of simple test data, the methodology of longevity prediction of materials under arbitrary thermally and forced effects is considered. The methods of thermally activated analysis of strength tests results of duralumin and boron plastic are considered with regard to low temperature effects of failure. The correcting for the effective temperature that take account of these features, is been refined values of activated parameters of the process. Thermally activated analysis of experimental data should also take into account the quantum features of low-temperature fracture kinetics. In processing the experimental data, temperature correction is necessary to insert as it takes into account the low-temperature features of fracture, and in some cases changes the method of processing. It specifies the value of activation parameters of the process, which are used later in equations of physical warping and fracture kinetics under durability and longevity prediction of materials in constructions.
